Hi, All
When Canonical HRF with time and dispersion derivatives is used for
within-subject analysis with SPM2, how can I get the best contrast vector (not the
contrast matrix for F statistics) between the task and baseline condition? I think
neither [1 0 0 ] nor [1 1 1] is the best and I wonder if there is a better
choice?
Best,
